A chord 12 cm long subtends an angle
of 40° at the centre of the circle. Calcu-
late the radius of the circle.
Answer:
Chord 12 cm long subtends an angle of 40 degrees at the center of a circle.
θ= 40° = 0.698 rad
Let R be the radius of circle.
Chord Length = 2Rsin(θ/2)
12=2R sin (0.698 /2)
R= 17.54
Ans: Radius of circle = 17.54 cm
the ages of three siblings are all consecutive integers the sum of their ages is 39 how old is the youngest sibling variable equation solution
Answer:
Step-by-step explanation:
Let x = the age of the youngest child
Let x + 1 = the age of the middle child
Let x + 2 = the age of the oldest child
x + x + 1 + x + 2 = 39
3x + 3 = 39
3x = 36
x = 12 years
A baseball team bought 8 boxes of baseballs. If team spent a total of 2,696 what was the cost of 1 box of baseballs?
Answer:
337
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Total number of boxes bought = 8
Total amount spent = 2,696
So, we can calculate the cost of 1 box by using following formula
Cost of 1 box = Total amount spent ÷ Total number of boxes bought
By putting the value, we get
Cost of 1 box = 2,696 ÷ 8
= 337
Hence, the cost of 1 box is 337.

How to form two-way table?Suppose two dimensions are there, viz X and Y. Some values of X are there as X_1, X_2, ... , X_n and some values of Y are there as Y_1, Y_2, ... , Y_n
List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:
Value(ith row, jth column) = Frequency for intersection of X_i and Y_j (assuming X values are going in rows, and Y values are listed in columns).
Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.
For n = 2, and k = 2, the table would look like:
[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]
where S denotes total of totals, also called total frequency.
n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.
We are given that;
Number of dogs playing=3232
Number of puppies=1515
Now,
We can calculate the number of dogs that have long hair by using the information that there are 66 more dogs that have long hair than dogs that do not have long hair. We know that there are 1111 dogs that have long hair and 1717 dogs that are not puppies. So, the number of dogs that do not have long hair is 1717 - 66 = 1651.
We can also check that the total number of dogs is equal to the sum of the number of puppies and the number of not puppies. 1515 + 1717 = 3232.
Therefore, the table will be;
Dogs Puppies Not Puppies Long Hair Not Long Hair

Point P on line segment AB partitions AB into a 2:3 ratio. What fraction of the line segment is to the left of point P? *
Answer: [tex]\dfrac{2}{5}[/tex]
Step-by-step explanation:
Given
Point P lies of line segment AB and divides it in 2:3
The entire length is divided into 5 parts, 2 is the left side of P and 3 parts are right of P.
Therefore, the fraction of length which is left of P is
[tex]\Rightarrow \dfrac{2}{2+3}=\dfrac{2}{5}[/tex]
Juan's time in the race was 5.04 seconds and Tiauna's was 5.40. Explain who had the faster speed and by how much?
Answer:
speeds of Juan and Tiauna are 0.1984 m/s and 0.1851 m/s respectively
Step-by-step explanation:
Given: Juan's time in the race was 5.04 seconds and Tiauna's was 5.40 seconds
Let speed of Juan and Tiana's be J m/s and T m/s respectively
In the race both Juan and Tiauna will cover equal distance. Therefore, the speed and time would have reciprocal relationship
Speed ∝ 1/Time
This means J = 1/5.04 m/s
J= 0.1984 m/
and, T = 1/5.40 m/s
T= 0.1851 m/s
Therefore, speeds of Juan and Tiauna are 0.1984 m/s and 0.1851 m/s respectively

please solve the equation: 11a-(4a-7)=77
Answer:
a=10
Step-by-step explanation:
11a-(4a-7)=77
11a-4a+7=77
7a+7=77
7a=70
a=10
Answer:
a=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
11a−(4a−7)=77
11a+−1(4a−7)=77(Distribute the Negative Sign)
11a+−1(4a)+(−1)(−7)=77
11a+−4a+7=77
(11a+−4a)+(7)=77(Combine Like Terms)
7a+7=77
Step 2: Subtract 7 from both sides.
7a+7−7=77−7
7a=70
Step 3: Divide both sides by 7.
[tex]\frac{7a} {7} = \frac{70} {7}[/tex]
Thus a = 10
Two pentagons are similar. The area of one of the pentagons is 9 times
that of the other. Determine the ratios of the lengths of the corresponding
sides and the perimeters of the pentagons.
Answer:
The ratios of the lengths of the corresponding sides of the two pentagons is 3:1
The ratios of the perimeters of the two pentagons is 3:1
Step-by-step explanation:
Let the first pentagon be X and the second pentagon be Y.
Ratio of area of the two pentagons is [tex]\frac{A1}{A2} = \frac{9}{1}[/tex]
Ratio of sides of the pentagon is equal to
[tex]\frac{S1}{S2} = \sqrt{\frac{A1}{A2} }\\=\sqrt{\frac{9}{1} } \\=\frac{3}{1}[/tex]
Ratio of perimeters is equal to ration of sides
Hence,
[tex]\frac{P1}{P2} = \frac{3}{1}[/tex]

According to the article, the pancake map is better than 2D maps made in the past. Which paragraph BEST supports this idea?
Group of answer choices
) Creating accurate 2D maps has troubled map makers for centuries. To help determine the various problems flat maps face, Gott worked with David Goldberg, a professor of physics at Drexel University in Philadelphia. In 2007, they published a system that rates existing flat maps.
Their system scored 2D maps on their deformations, or distortions. It scored six types of distortions: local shapes, areas, distances, flexion (bending, or distortions of curves), skewness (lopsidedness), and boundary cuts (gaps in landmasses or water, like splitting the Pacific Ocean). Maps that received lower scores were more accurate. A globe, which is spherical like the Earth, would earn perfect scores of zero.
Flat maps are good at representing one thing but not others. Take the world map most people are familiar with — the Mercator projection. This map is good at representing local shapes, it distorts surface areas near the North and South Poles, so these regions are often chopped off.
) The pancake map also has smaller distance errors than any other 2D flat map. For instance, its layout means distances cannot be more or less than 22.2 percent of what they are in reality, Gott said. In comparison, the Mercator and Winkel Tripel projections have remarkably high distance errors near the poles and at the left and right edges of the map.
Answer: The pancake map also has smaller distance errors than any other 2D flat map. For instance, its layout means distances cannot be more or less than 22.2 percent of what they are in reality, Gott said. In comparison, the Mercator and Winkel Tripel projections have remarkably high distance errors near the poles and at the left and right edges of the map.
Step-by-step explanation:
A better map is one that has less errors and can locate areas more accurately. The paragraph above shows that the Pancake map has less errors and is generally accurate for areas within a 22.2% band.
This means that it is better than 2D maps made in the past especially the Mercator and Winkel Tripel projections which have some very significant distance errors especially in relation to the poles and the edges of the map.
